Mix together all of the chicken rub ingredients. Place them with the chicken in a plastic ziplock bag or container and shake to completely coat the chicken. Grill the chicken (I use my George Foreman Grill), or if you don't have a grill, you could saute it as well.

Put the cooked chicken on a cutting board and use two forks together to pull the meat apart, shredding the chicken. Set aside.

Spray a pan with cooking spray, and saute the garlic, green peppers, and mushrooms until tender.

Heat the tortillas in a microwave (about 10 seconds). Place on a plate and spread with guacamole. Top with chicken, vegetables, and salsa. Roll up and enjoy!
